- rectly tothe briquettes in theinterior. v Y A* v l c The inventionis shownl as applied to 'an CONVEVER BUCKET i930. seriai No. ceases.,

`ticularly in the treatment of briquettes formed of ground coal andthe like which havebeen passed through an ovenl having" ftwo: or-more zones' in which the briquettesy are first subjected to a distilling processrv to remove the volatile products' and afterwards subjected to a bakingor hardening process for the purpose of bringing them 'into a hard Acondition suitable for handling and ship-V .ment. Heretofore the briquettes have been conveyed through'thevarious Zones in this-l furnace in baskets which 'held the briquettes Vf j The outside bri#v quettes protects-those in the interior from the heat'and the gases in -this oven.v Thereforer there was danger that the briquettes at the center of the baskets would not be treated tok exactly the same extent as those on the outf Thus the product was not strictly uni;-` form..l i i This invention is made particularly for the purpose of securing uniformity in results, withadditionalcapacity getting the body of briquettes in the buckets or baskets into a form in whichthe heat and gases will have access to all the briquettes in a substantially uniform manner and there will be no center or` core of the mass or bodyof briquettes that l willbe protected in anyway. by the outside layer.` This is done'by dividing the body of briquettes iny eachbasket up vinto a plurality of'mass'es which fare of comparatively flat shape Yand of thin Across section in one direc#Q tion so the heat and gases will penetrate endless chainfconveyer comprisingtwo sta? tionary tracks 1:0 suitably supported, rollers 11 mounted to roll on the tracks and a seriesl of links l2 pivot'ally connected with thevroll ,f

ers'and constituting two double chains` The rollers. arey mounted onaxles 1K3 Whichare connected with the baskets 14 at their `vends by securing'them thereto in any desiredy man# nenasgforjexample, by means ofv capsfl s'e-j cured to the ends of the baskets I'and tov the axles. The baskets can befreely pivoted on theseaxles'or securedthereto as may be convenient. "The ends of theseaxles pass through the lllkSlZ soas to connect themtoge'ther.

parallel shafts k17 Vprovided ywith pinions or gear segments- 18 intermeshing so that the two shafts are obliged to turn simultaneously when they do turn. Each shaft also is provided with a plate 16 'and these plates are shown as located substantially horizontally"A at'about the center of the basket.k Stops 19 are provided so that these plates can rest upon them as'shown. Itwill be understood that the baskets are inverted in any usual way for discharging the contents. i

At the left ofFig. 1 `n the part of the view which is a side-elevation, these plates 16 are shown as extending upwardly and they are bent or odset slightly so that they can pass around the axle 13 and come together at thevv V top so that the basket vcan be filled on the the position shown Aat `the-right hand end. ofy

bottom from a chute 2O as shown and notl interfere with these plates standing up in this position. filled-with briquettes up to a point lower than the elevation of the shafts 17, the ltwo .plates 16 are swung backwardly with their shafts to Fig. 1 in section. This isV accomplished by an arm 21 on the end of one of the shafts 17 coming into-contact with `a stationary dog-22 as the conveyer moves along from left to right in Fi-gfl. Y

When the plates are moved back to the horizontal position the filling continues and the result is' that the second layer of briqu ettes is deposited on these platesand the basket is able to carry about asmanybriquettes as lit would if the plates were not present.v .but there is an airspace between the bottom layer andthe plates 16. This enables Vthe heat and also the gases to get atthe briquettes and there is no body of briquettes of larger width than substantially half the height of the basket.

Thereforefthe heat can penetrate into theY mass and there is no body of n iaterialV at the center of the :mass that might notV be thoroughly subjected tothe heatingaction.L VIf it-is desired to have gases or airV penetrate into this body ofbrijquettes, theplates 1.6 can be perforated as indicated in Fig. 1 and also 1 the bottom lof the basket can be provided with perforations for the same"purpose.. That,V however, is not V essential where the :ideafis .to

secure auniform treatment byfheat, particularly thebriquettes are to berheated by indirect'heat insteadrof by the direct v:heat of the products of combustion.

Y Y.In Y:the form of the'invention .as

After thefbottom of the basket is Figs and 4, an equivalent arrangement is shown in which the buckets or baskets 25 are pivoted on an axle 26 and depend therefrom as before. There are two separated shafts 27 each having a plate 28 extending inwardly and resting on the stop 29. These plates are provided with arms 30 projecting therefrom and constituting counterweights which are thrown upwardly by opening trips 31 and downwardly by closing trips32. When up they restagainst stops 33 and furnish upwardly projecting walls at the opposite ends of the baskets to guide the material down into the baskets. They are operated in a way that will be readily understood from the description given above vof Figs. 1 and 2.

In Fig. 5 I have'shown the Vbasket on the same principle as that shown in Fig. 1 but in addition to the lower plates 16'there is an upper pair 'of shafts 37 Y carryingy plates 38 adapted `tovrest on stops 39 and to move into the dotted line position for filling.

It will be understood that in all cases the tilting of the baskets bottom side up will bring the plates into the vertical position and they are held there by friction and gravity as'they, extend inwardly over the axle 13 even after the baskets are turned back to upright position Y and are swung down only by the various trips and dogs employed for engag ing thearmson the ends of the shafts 17, 27 and'?.v

' This invention, although described as being designed lparticularly for the treatment of ground coal'briquettes, is capable of being employed for any other uses in which the material to be conveyed is intended to be sub-V jected to heat,cold or gases.k Although I have 'illustrated and described only three forms ofthe invention .I amaware of the fact that other modifications can bemade therein by any person skilled in the ,art without vdeparting' from the scope of the invention as expressed in thefclaims. Therefore I do not wish to be limitedV in this respect but what I do claim is 1v. In -a conveyer, the combination with a track, rollers movable along said track.'y axles for said rollers, and chains connected with the axles `for drawing them along, of `receiving baskets pivotally depending from said axles andrsupported thereby, plates located in said basketsV and constituting floors, and stationary means along the track formoving said l plates into and out of horizontal position for supportingv material, as the chains move along;

2. In a c onveyer,the-combination with I stationary ftrack, of rollers mounted thereony to roll along the-track, chains connected with the Y rollers fork operating them, said rollers iaving axles projecting inwardly toward each other, baskets pivotally supported by said axles, a pair of shafts in each basket, a plate connected with eachshaft tomove therewith lai into and out of substantially horizontal position so that when in that position they constitute floors for receiving material, said shafts being oscillatable, projections on said shafts E and stationary dogs along the tracks for turning the shafts to two dierent positions in one of which they act as means for supporting the Y material and in the other of which they move out of the way so that material can be deposited past them on the bottoms of the lo baskets.

3. A basket for a conveyer comprising a containing body having a bottom, a plate located above said bottom, means for movingk said plate into two limiting positions in one of which it is spaced above said bottom to receive material thereon and transport it and in the other of which it is located out of the way so that material can be deposited directly on the bottom of the basket.

4. In a conveyer basket for the purpose described, the combination with the body of the basket having a bottom for receiving the material to be conveyed, of a pair of plates pivv oted near the center of the basket and adapted to extend in opposite directions to furnish a iioor above the bottom for receiving material to be conveyed, gear teeth connected with the two plates and intermeshing so that the two plates will be forced to turn simultaneously and a projection connected with one of the plates and adapted to be operated from the exterior of the basket to turn both plates.k

5. As an article of manufacture, a conveyer basket having a bott-om for receiving material to be conveyed and means above the bottom for receiving a second'layer of material to prevent the depositing in the basket of a body of material having a depth sutticient to prevent the action of heat or gases on any material at the center thereof, said means being adapted to swing upwardly inthe bucket to permit dey positing the materials on said bottom from above.

In testimony whereof I have hereunto affixed my signature.
